What I am about to say may upset some people. Who ever the idiot was who came up with the idea of a piston fired pellet gun need to be shot! I put almost 750 round threw this thing today. It jumps way too much when fired at 10, 20 and 30 yard ranges I couldn't even get a shot within 2 inches of what I was aiming at. I am done with NP rifles completely! I put my scope on my friend's Remington 270 and hit the center of the target 4 out of 5 times with a grouping of 1/2 inch at 30 yards. It's not the trigger that is the issue it is that stupid piston slamming before the pellet leaves the barrel. If what I said offends anyone I am sorry but these things not so good!!!
